Surface mineraliser and hardener for all porous mineral materials - waterproofing and stain repellent

Mineralises and consolidates.

• Guard Hardener Dry Surface is designed for the consolidation of crumbling porous mineral materials: siliceous and carbonated rocks, concrete, cement, bricks, terracotta, molasses… It can also be used for the renovation of ancient monuments, fountains, cornices, and natural stone statues.
• Guard Hardener Dry Surface is a remedy for the main causes of material deterioration such as freeze-thaw cycles and acid rain, damage due to salt (crystallisation, hydration, hygroscopy), material dilatation and contraction, and limestone carbonate structure alteration caused by water containing carbon dioxide, moss or lichens…
• Guard Hardener Dry Surface recreates the crystalline structure destroyed by one of the above-mentioned causes in order to have the treated substrate regain its original mechanical properties, without modifying its appearance or permeability to air.

Water-repellent and oil-repellent.

• Guard Hardener Dry Surface also has water and oil-repellent properties that enable it to sustainably and permanently protect porous materials against the penetration of water, oil and staining.
• Guard Hardener Dry Surface delays the aging of substrates, makes their maintenance easier and helps to prevent main causes of degradation such as atmospheric pollution, greasy soiling, water penetration, etc.
